Theory of Continental Drift - adjudicate ExampleSome of the bear witness gathered in the last part of the twentieth century to bear the supposition of continental drift includes the glacial till deposits. With the continents in their current locations, the till deposits tend to period towards an inconsistent glacier kinesis. Fitting the continents together reveals a more reorganized motion of the glaciers from the southern Africa region to northerly Australia outward (Bugielski, 1999). Paleontologists disc all overed fossils of species that bore similarities to other species that are in continents now isolated by abundant distance. Paleoclimate studies, a science dealing with the study of the earths climate in the periods past discloses that glaciers stretched over large tracts of the world which are now rendered apart by colossal geographic spans. This show appears to prognosticate to the fact that the lithosphere had been travelling over geologic time. A Paleomagnetic study, which investigates the Earth,s past magnetic activities overly tend to strongly support the speculation of continental drift. Studies show that the magnetic north pole ostensibly strolled all over the earth, indicating that either the tectonic plates or the North rod cell was moving. But because the North Pole is in effect fixed with the exception of cycles of magnetic reversal, this evidence becomes a strong endorsement of the guess of continental drift. More evidence surfaced in the wake of World War II when seismometers were set up to check nuclear testing. These gadgets revealed that volcanoes and earthquakes aligned along apparent belts around the globe and that these belts delineated the boundaries of tectonic plates. Scientists jilted Wegeners ideas then because he did not explain why and how the continents moved, he just provided observational evidence that they had indeed moved. In the absence of reasonable physical mechanism to support continental drift, many scient ists merely found the idea unacceptable. Back in his times, many scientists were of the conviction that the structure of the earth was because of the earth deprivation through successive phases of heating and cooling that resulted in the expansion and contraction of landmasses (Aber, 2007). If they were to believe Wegeners theory, it would think up that they would have to forget everything that they had learnt and start all over again. As time passed, increasingly more evidence supporting continental drift became available and more practitioners had to align themselves with this new sphere of knowledge. These ideas accentuate the theory of an ocean floor that evolves and repositions. This theory is popularly known as Plate Tectonics. scientific method relates to techniques for investigate events, obtaining new and novel knowledge and re-examining the earlier knowledge and beliefs. The key attribute that differentiates a scientific method from any other method of knowledge acqui sition is the fact that knowledge is gained through evidence and proof. Scientific method comprises four main coiffures The first is the examination and explanation of phenomena followed by the construction of a theory to account for the same phenomena. The third stage is the use of the theory to, quantitatively, predicts the outcome of new observations. The final stage is the piloting of thoroughly conducted experiments on the predictions by several competent and impartial experimenters and finally a ending regarding the outcome of such experiments
